.To all whom it may concern:

Be it known that I, ROBERT C. LAWHEAD, a citizen of the United States, residing at Allu-we, in the county of Nowata and State of Oklahoma, have invented certain new and useful Improvements in a Guide, of which the following is a specification.

This invention relates; to rope winding apparatus and has specialreference to that class of apparatus known .as hoists or apparatus wherein. a rope carrying a Weight at its free end is wound and unwound upon suitable drum or Windlass provided thereor.

The object of the invention is to provide in a rope winding drum, means for automatically guiding the rope during the operation of winding and unwinding, and to so construct and organize the parts of the guide means as a whole, that the preceding coils of rope will be wound upon the drum with the utmost precision and with uniform veand whereby the preceding coils" of locity,

the rope will also be wound contiguous and in planes parallel with each other. v

heinvention still further resides in the provision of means of the nature above set forth wherein a shifting and adjusting of the said. means may be efiected to increase the scope of its usefulness. A

The above and additional objects are accomplished by such means as are illustrated in their preferred embodiment in the accomthe drawings,

panying drawings, described in the following specification and then more particularly pointed out in the claimswhich are appended hereto and forms: part of this applica: tion. In describing my invention'in detail referings wherein like characters denote like or corresponding parts throughout the several views, and in which:

Figure 1 is an elevation illustrating the application of the invention in connection with a hoist for derrick; Fig. 2 is a viewv illustrating the detail construction of the gulde device; Fig. 3 is a detail view of the guide support; Fig. 4 is an enlarged elevation of one of the adjustable bands or collars carried by the support; Fig. 5 is a section on the line 55 of Fig. 4; and 6 is a view vice;

Before proceeding with the description of I desire to call particular atence will be had to the accompanying drawthrough which either of tention to the fact that while I have evolved my invention Withparticular reference to its application in connection with a well pulling machine as a guide for the operating rope associated therewith, the same may be readily utilized as a guide means in connection with various types and forms of winding apparatus wherein one or used.

Referring merals, it will be seen that the machine consists of an upright or derrick 1 comprising the usual base support 2 and brace beam or beams 3, the latter being disposed in a plane above the usual drum shaft 4 and drums 5 and 6 respeetiveiy, mounted thereupon. A substantially U-shaped support member or bracket 7, the extensions of which are screw threaded as at 8 is detachably secured to one of the brace beams or supports 3. The threaded extremities 8 of the extensions of the said bracket pass through openings 9 of the beam 3, nuts 10 being threaded upon the said extensions to retain the said bracket in place. By enlarging the extensions as at 11 and disposing the said enlargement against one face of the said beam as illustrated to advantage inFig. 3 of the drawings, it is apparent that move ent of the support in one direction is limited thereby, the nut 10 serving as ameans whereby movement in the opposite direction is prevented. Adjustable collars or bands 11, preferably two in number, are loosely mounted upon the said support 7 and locked in adjusted position thereupon through the medium of set more drums are screws or bolts 12 adapted for engagement continuing as one as indicated at 16 until finally terminating in a coiled or helical ex tension 17, the latter providing a loop the ropes 18 01-19 of the hoisting apparatus are adapted to pass. The diverging extremities of the arms 14 each terminate in an eye 20 arranged to embrace the said support 7 to eifect a'loose connectionfor the said guide.

Referring now to the modified form of guide device illustrated in Fig. 6, the nu- 65 now to the drawings by numeral21 designates the said guideas an entirety, at one end of which an eye 22 is formed and at the opposite end a coiled or helical extension 23 is formed, the lat v ter serving the same purpose as theexten sion 17 of the converged guide means, and the former the same purpose as the "eye 20 aforesaid. The said guide member being.

loosely mounted upon the support 7, and ar-' ranged to loosely embrace the rope or cable acted upon, it is apparent that the latter during a winding or unwinding operation will be guided back and forth to wind upon the drum with the utmost precision, the said rope or cable. By adjusting the collars or bands 11 it is apparent that the path of movement of the guide device 13 may be limited to suit the demand made thereupon, or to correspond with the size of the drum over which the cable or rope acted upon is arranged.

From the above, taken in connection with the accompanying drawings it is apparent that by providing a support 7 of a size to extend beyond the extremities of the respec-,

tive drums, that the said guide device ma be removed from engagement with the cable of one drum and quickly shifted to the cable of the adjacent drum by simply adjusting the collars or hands 11 longitudinally of the support or bracket from which the guide device is hung to depend.

To fit the cable within the loop formed by the coiled extension 17 of the guide means, all that is necessary is to first pass the said rope in the space indicated a, then over and into the space indicated 6, and finally into the space indicated 0, in which event the rope is entirely surrounded or embraced in such a way as to be subsequently guided back and forth from one to the other end of the drum in the desired manner.

It will be understood that the above .description and accompanying drawings com; prehend only the general and preferred embodiment of my invention and that various minori phanges in details of construction,

proportion and arrangement of parts may be made within the scope of the appended claims and without sacrificing any of the advantages of my invention.

Havin thus fully described my invention,

what ll 0 aim as new and desire to secure by Letters Patent, is

1. In combination, axially alineddrum's, each drum having a flexible element wound thereon, supporting means for the drums, a bracket mounted on said supporting means,

the bracket extending arallel with the axes of the drums, a pair 0 relatively adjustable single guide device hung to depend from the bracket and to removably engage one or the other of said flexible elements, said guide device being limited in its movement by the stop means aforesaid, as and for the purpose set forth.

2. In combination with a plurality of drums arranged in axial alinement, each engageable with the element acted upon,'

said coiled portion of the guide being movable vertically and longitudinally relatlyely to the drum during a winding and unwlnding operation, as and for the purpose set forth.

In testimon whereof I afiix in presence 0 two witnesses.
